Through online banking, it is found that the card of China Bank has more than 18 yuan one day. I'm sure it's not for my own use, and I haven't received the SMS reminder.

You can call 955 16 unionpay first to ask. If you can't find it there, you can only go to the bank. If you want to know the bank, just call 95566 and report the card number. Then go to the bank to check.

Is it 18 yuan? Either you have an annual fee of 2 years. Until then, you have a 2 yuan balance in your card. Because the deduction is incomplete, you first deducted 2 yuan, and then recently you have money in your card, and then deducted the rest 18 yuan. SMS service monthly function in 3 yuan, monthly or annual, without half-year deduction for package 18 yuan. Good luck.
